The Intel® Pentium® 4 processor 660, 650, 640, and 630Δ (this model is 660) on 90 nm process in the 775-land package and the Intel® Pentium® 4 processor Extreme Edition on 90 nm process in the 775-land package are follow-ons to the Pentium 4 processor in the 478-pin package, with enhancements to the Intel NetBurst® microarchitecture. These Pentium 4 processors on 90 nm process in the 775-land package use Flip-Chip Land Grid Array (FC-LGA4) package technology, and plug into a 775-land LGA socket, referred to as the LGA775 socket. The Pentium 4 processor 660, 650, 640, and 630 on 90 nm process in the 775-land package and the Pentium 4 processor Extreme Edition on 90 nm process in the 775-land package, like their predecessor, the Pentium 4 processor in the 478-pin package, are based on the same Intel® 32-bit microarchitecture and maintain the tradition of compatibility with IA-32 software.
